History .............................................................................................................................................77

This European Telecommunication Standard (ETS) has been prepared by the Radio Equipment and

Systems (RES) Technical Committee of the European Telecommunications Standards Institute (ETSI).

Annex B contains normative specifications for adjacent channel power measurement arrangements.

Annex C is a graphic representation of subclause 4.1, referring to the presentation of equipment for testing

Annex D contains specifications for the test discriminator used in transient measurements.

- the type test measurements performed in an accredited test laboratory in one country would be

accepted by the type approval authority in another country provided that the national regulatory

- if equipment available on the market is required to be checked it should be tested in accordance

This ETS is intended to specify the minimum performance and the methods of measurement of radio

equipment for use in the land mobile service as specified in this scope. Clause 5 provides the

corresponding limits. These limits have been chosen to ensure an acceptable grade of service and to

minimise harmful interference to other equipment and services. They are based on the interpretation of the

This ETS covers the minimum characteristics considered necessary in order to make the best use of the

available frequencies. It does not necessarily include all the characteristics which may be required by a

user, nor does it necessarily represent the optimum performance achievable. It applies to non-speech and

to the non-speech part of combined speech/non-speech equipment with integral antennas, used in constant

envelope angle modulation systems in the land mobile service, operating on radio frequencies between 30

This ETS, which is based upon CEPT Recommendation T/R 24-01 annex VI [1], is a general standard

In this ETS, a non-speech radio equipment is defined as a radio equipment transmitting a signal to initiate a

specific response in the receiver. The equipment comprises a transmitter and associated encoder and/or a

receiver and associated decoder. The encoder and/or decoder may be a separate piece of equipment, in

which case compliance to this ETS covers the combination of encoder and/or decoder and transmitter

In this ETS different requirements are given for the different radio frequency bands, channel separations,

The type of equipment covered by this ETS is handportable stations with integral antennas.

This ETS is complementary to I-ETS 300 219 [2] which covers radio equipment with an internal or external

RF connector transmitting signals to initiate a specific response in the receiver, for use in the land mobile

For combined speech/non speech equipment this ETS is complementary to ETS 300 296 [8] which covers

radio equipment using integral antennas for use in the land mobile service intended primarily for analogue

Channel separations, maximum transmitter effective radiated power, the type and characteristics of

modulation and the inclusion of automatic transmitter shut-off facility may be conditions required for the

Equipment which also includes an external or internal RF connector should be type tested to the

In the case of combined speech/non-speech equipment the speech part should be tested to the

requirements of ETS 300 296 [8] and additionally the tests described in the following subclauses of this

These requirements also apply for equipment with an analogue output facility provided for test purposes

Where an equipment has already been type approved to ETS 300 296 [8], and is resubmitted for type

testing to this ETS, additionally the tests described in the following subclauses of this ETS should be

Additional standards or specifications may be required for equipment such as that intended for connection

This ETS may also be used by accredited test laboratories for the assessment of the performance of the

equipment. The performance of the equipment submitted for type testing should be representative for the

performance of the corresponding production model. In order to avoid any ambiguity in that assessment,

this ETS contains instructions for the presentation of equipment for type testing purposes (clause 4),

This ETS incorporates by dated or undated references, provisions from other publications. These

normative references are cited at the appropriate places in the text and the publications listed hereafter.

For dated references, subsequent amendments to or revisions of any of these publications apply to this

ETS only when incorporated in it by amendment or revision. For undated references the latest edition of
